Envelope wall is set, and in the pre-buried vacuum tube in cofferdam bottom.It is laid with the sand bedding course of one layer of suitable thickness, inside arrangement chimney filter and vacuum
Pipe, surface cover geotextiles.Plastic draining board is set, and one section of drain bar crop out is tied up vertically in moso bamboo frame upwards
On.Dredger fill sandy soil is to absolute altitude.Vaccum-pumping equipment is installed, vacuum diaphragm is laid with.It starts vacuum pumping pump and reaches the design degree of consolidation in the soil body
Afterwards, that is, it comes to an end.Although the invention increases the consolidation process depth of vacuum preloading;Shorten the construction week of project of reclamation by pumping filling
Phase;Save vacuum membrane material.But construction method is more complicated, cost is higher.
The Chinese patent of 102926376 A of Publication No. CN discloses a kind of method of reclaimed ground processing, specifically relates to
And one kind is reclaimed fields from the sea region soft-soil foundation treatment method, concrete scheme is: in deep level of processing region, being formed in hydraulic reclamation soil layer
Before set long plastic draining board, it is default that long plastic draining board height is made to be higher than hydraulic reclamation soil layer absolute altitude;Hydraulic reclamation soil layer shape is completed later
At;Short plastic draining board is set in non-deep level of processing region later;Last large area piecemeal carries out vacuum preloading.
Although the processing of one step of this method is in place, accelerate deep Soft Soil Layer as load using barged-in fill during hydraulic reclamation
The duration is saved in consolidation settlement, reduces cost, reduces the problem of conventional point multistep reprocesses waste in place.But it is carried out
Discharging consolidation effect is not it is obvious that finally influencing whether our foundation stabilization.
Summary of the invention
In order to solve current reclaimed ground, there are the above problems, and the invention proposes one kind to reach well
To the purpose of reinforcing, and have structure simple, low cost, convenient for the barged-in fill drain consolidation system of construction and installation and its construction
Method.

Surface be laid with one layer of cationic active agent;The draining tube layer is made of several drainpipes, is distributed on the drainpipe
Several drainage holes;The filter membrane is coated on the surface of the drainage hole;The drain bar insertion hydraulic reclamation
In soil layer and the draining tube layer, and drain bar height is higher than all hydraulic reclamation soil layer absolute altitudes, i.e., described drain bar
The barged-in fill layer surface of top edge exposing top layer.
Cationic active agent is the substance that target solution surface tension can be made to be remarkably decreased, and can reduce by two kinds of liquid or liquid
Surface tension between body-solid, greatly improves the effect of draining, and Direct Uniform is layered on barged-in fill layer surface.
The drainpipe is groined type.
The filter membrane pricks non-woven fabrics using long fine heat.
The drain bar extends vertically through the hydraulic reclamation soil layer and the draining tube layer.
A kind of construction method of barged-in fill drain consolidation system of the present invention, comprising the following steps:
1) the hydraulic reclamation soil layer of the bottom is completed, and is laid with one layer of cationic active agent on surface;
2) drainpipe is arranged on the hydraulic reclamation soil layer completed, and forms draining tube layer;
3) one layer of hydraulic reclamation soil layer is filled on the surface of draining tube layer, and is laid with one layer of cationic active agent on surface;
4) it repeats step 2), 3) forms multilayer discharge structure, guarantee that hydraulic reclamation soil layer is arranged alternately with draining tube layer, the bottom
It is hydraulic reclamation soil layer with top, and outside the barged-in fill layer surface of top, the surface of hydraulic reclamation soil layer described in remaining every layer
It is laid with one layer of cationic active agent;
5) drain bar is set, keeps drain bar to extend vertically through hydraulic reclamation soil layer and pvd layer, wherein drain bar height is higher than
The barged-in fill layer surface that all hydraulic reclamation soil layer absolute altitudes, the i.e. top edge of the drain bar expose top layer.
The beneficial effects of the present invention are: (1) is placed on plastic drain-pipe between barged-in fill by hydraulic reclamation stage by stage, is mentioned
The high drainability of barged-in fill, preferably improves the consolidation effect of reclaimed ground, with easy to process and construction and installation
Advantage;The present invention is suitable for the basement process of barged-in fill;(2) filter membrane coated on drainpipe pricks non-woven fabrics using long fine heat,
With resistance to flooding, permeability performance is extremely excellent.Major function is to shorten drainage distance, accelerates draining.The plastic draining board,
The good vertical channel of moisture when it is basement process greatly shortens the consolidation time of soil.
